Technically, it was a mere division of the Office of Public Safety. It had a reputation for creatively misconstruing directives with which it disagreed, which is why its critics pronounced the MISD acronym "missed".
The basic operational MISD unit was a regiment, consisted of two battalions of c.a. 1000 troops. As of 1922 PD Regiments 4 and 19 were stationed in the Capital District. During the Operation Rat Catcher they were supported by 17th Regiment.
